Orland Fire Protection District paramedics assisted two dozen patrons suffering from carbon monoxide poisoning while dining at a Red Robin restaurant in Orland Park Friday night.

According to a statement released by the district early Saturday, emergency crews responded to the location at 15502 S. LaGrange Road after customers complained of headaches and feeling sick.

Four people were transported to Silver Cross Hospital in Mokena, according to officials, where their condition was unknown as of Saturday morning. Twenty others were evaluated by paramedics.

The restaurant was evacuated by customers and employees as firefighters found “high levels of carbon monoxide” and traced it back to HVAC units, according to the statement.

“Officials of (Nicor Gas) and the Village of Orland Park Building Department were called in and the restaurant was shut down for the evening,” the statement added. “Officials said the restaurant will remain closed pending completion of repairs.”
